None of the string methods modify this
– they always return fresh strings.

charAt(pos: number): string
ES1Returns the character at index
pos
, as a string (JavaScript does not have a datatype for characters).str[i]
is equivalent tostr.charAt(i)
and more concise (caveat: may not work on old engines).
This document details how I setup LE on my server. Firstly, install the client as described on http://letsencrypt.readthedocs.org/en/latest/using.html and make sure you can execute it. I put it in /root/letsencrypt
.
As it is not possible to change the ports used for the standalone
authenticator and I already have a nginx running on port 80/443, I opted to use the webroot
method for each of my domains (note that LE does not issue wildcard certificates by design, so you probably want to get a cert for www.example.com
and example.com
).
For this, I placed config files into etc/letsencrypt/configs
, named after <domain>.conf
. The files are simple:
user web; | |
# One worker process per CPU core. | |
worker_processes 8; | |
# Also set | |
# /etc/security/limits.conf | |
# web soft nofile 65535 | |
# web hard nofile 65535 | |
# /etc/default/nginx |
window.navigator.language // -> "fr" | |
window.navigator.languages // -> ["fr-FR", "fr", "en-US", "en", "es", "de"] | |
window.navigator.userLanguage // -> undefined | |
window.navigator.browserLanguage // -> undefined | |
window.navigator.systemLanguage // -> undefined |

A Stylus mixin for linear gradients with support for comma-separated splat arguments. In part created as a work-around / abstraction for this.
The method for retrieving the fall-back background colour can do with some improvement, such as averaging the colours or selecting a colour by means of passing an additional argument.
